lthesides of the receptacle be cylindrical-and this inclined bottom be a plane, it will have A As represented in the the upper part of the receptacle into a single shaitfl 9, which has a beveled gear f2.04 driven by another beveled gear 21, and sliaftQ): and

crank These driving parts are mounted l on a strap or cover 2st set across thetop ofthe receptacle. The shaft 19 isv also supported from th'isfstrap Qi, the hub otgear Thus, the inclined bottom' 15, the arms 16, 17 supporting it, and the shaft 19, are all removable from the receptacle, with the strap Q11 and driving mechanism thereon. The lining 11 may also be removable if desired. Upon rotation of- 4the crank 23. and shaft 22 the inclined bottom 15 is rotated about the axis of shaft 19,'-

which is the axis 'of the receptacle, the lining 11 remaining stationary.

, In operation, asmall amount of Water is placed in the receptacle, and a quantity of potatoes or other vegetables. Crank Q3 is then rotated in either direction desired. .in

interaction between the rotating inclined bottoni, t'h'e stationary walls, .and the water and-tithe solid contents then results, in the courseo which the individual potatoes are formed, with the water, into a mass which rises relatively high on the upright Walls,

and travels around in cont-.iet therewith. -Iiidividual potatoes rise through this mass in contact with the decorticating surface of the vreceptacle Wall, fall from-the top to theinclined plane, whence they rebound or are thrown back into the bottom ot' the mass and `Itoward the cylindrical 'walls under their felvlows, whence they are in turn -pushed upward by succeeding quantities of Water and individual potatoes which undergo the same experience. The potatoes impale themselves to a slight degree upon the decortieating surface of' the inclined bottom, but owing in part to its inclination and to its movement they are thrown from it, and in this respect the slight impaling upon the points assists.

rapid succession of impacts of eachindividual potato against various sharp -points .ofthe decortcating surface removes minute hits. of the skin, and the rush oli' water Queensland removes these bits both from the 'potato and fronithe impaling point, keeping lthe'.1:oi-ntfsalways tree, clear and sharp for action. Owing to the location of the arms of the fork at the sides midway of the incline, they assist in driving the body of p0- tatoes and water around the inner Wall of the receptacle, and at the same time afford a perfectly free inner space from Wall to wall;

and do not themselves obstruct the path of 1 l. A receptacle hating a rotatable bottom, l inrhned in the directi-:m ot its rotation, m j combination with walls of decorticating ma terial, and meanS to rotate the bottoni.

Q. A receptacle, having' a bottom rotatable with respect to the Walls and inclined in the (lirection of its rotation, and Walls harinI a l-i=.eular interior surface of deeorticating' material.

supporting arms rising;l from the edges of the bottom; an axial shaft to which the arm., are joined in the upper part ot' the recep tacle, and means to support and rotate said shaft.

'4. A receptacle, havingi` a rotatable bottom. inclined in the direction of its rotation with a decorticat'ing` upper surface, and circular walls rising close to its periphery, having;l a surface of decorticating material.

5. A receptacle, havingl a rotatable bottom, inclined in the direction of its rotation. with a decorticating upper surface. circular walls having an interior surface of decortieazing material; supporting arms rising from the periphery of the bottom approximately at iis widest level; and means lo rotate these arms about the axis.
